Abstract (en)
[origin: WO2013178390A1] The invention relates to an ultrasound sensor 100 which comprises a housing 101 with a peripheral side wall 102 and a base surface 104, thus being formed in a substantially pot-shaped manner. The base surface 104 is formed in a known manner as a membrane. A converter element 106, formed for example as a piezoelectric element, is disposed on the base surface 104 and serves to generate and detect ultrasound vibrations. According to the invention, at least one mass element 140a, 140b is disposed on the base surface 104 in such a way that the resistance of the mass element 140a, 140b to a vibration of the membrane increases as the vibration frequency increases.
